Provided is a production process for a carbonized product characterized by comprising the following steps (a) to (b):

Production process for carbonized product and carbonized product obtained by the same process

A process for production of 2,6-dimethylnaphthalene is disclosed, comprising the steps: (1) an acylation step where p-tolyl sec-butyl ketone is produced from toluene, n-butene and carbon monoxide: (2) a hydrogenation step where the carbonyl group of the p-tolyl sec-butyl ketone is hydrogenated: and (3) a dehydrogenation and cyclization step where the hydrogenated product obtained above is subjected to dehydrogenation and cyclization to produce the desired 2,6-dimethylnaphthalene. The process enables efficiently producing a high quality or high purity 2,6-dimethylnaphthalene.
